The Chris Waller trained Sambro was on his best behaviour to record a win in the 2018 Group 2 $350,000 Ascot Green Queensland Guineas (1600m) at Doomben today.

Sambro was a late scratching from the Group 3 $150,000 Sky Racing Fred Best Classic (1350m) at Doomben on May 26 when he reared up in the starting gates which resulted in his jockey Kerrin McEvoy being injured.

Waller sent Sambro for some retraining for the barriers and with the addition of a brow band, a woollie above the eyes, the Fastnet Rock three year old was on his best behaviour for jockey Michael Walker.

“He is a funny horse,” Waller said.

“Greg Bennet said that he had done a bit of work with him since his last start. He took him back to his place for two days, just fluffed around with him and gave him a bit of confidence and the brow band obviously above his eyes has stopped him rearing.”

“They don’t know what is up there, so that has been a big plus.”

“A you saw last start at Hawkesbury he was an impressive winner in the Guineas there pulled out that form today.”

After giving Sambro a winning ride, Michael Walker pulled up in a distressed state and has been stood down for the remainder of the meeting and will miss the ride on Foxplay in the Group 1 $1.5m Stradbroke Handicap (1350m).

Walker settled Sambro ($8.50) in a nice trailing position just behind the leaders and produced him in the straight with a clear run to hold out his stablemate Seaway ($5 favourite) with Magnugighter ($51) also running on for third.
